My daddy used to say, there's as many ways of learning guitar technique as there's lost picks in the universe :) Ok I made that up, but the point stands. At the end of the day, whatever works for you is the best solution

Having said that, I've spent the last few years reading up on memory retention, SRS and using Anki a lot for languages and what I've found is that Recall is extremely important for increasing the strength of the memory. With stickers and ribbons, the notes are right there for you. Like training wheels. Never challenging you to recall. Keeping you coming back for more of that ribbon help. ..you get the idea.
